Thanks for your insights. To contribute to your last question "Should evaluators make recommendations on communicating, their results?"
The answer of this question will depend on the circumstances and what the requester wants; if the evaluator is involved in research for instance, my answer is yes, making recommendations here shows the effectiveness of your results and the way forward. If you deal with policy makers , recommendations in communicating your results are ways to translate them into actionable policies. Recommendations also allow to clarify your results.
